NEWPARK RESOURCES REPORTS NET INCOME OF $0.15 PER DILUTED
SHARE FOR THE FOURTH QUARTER 2010

Company achieves record Operating Income of $78.0 million in 2010

THE WOODLANDS, TX — February 17, 2011 — Newpark Resources, Inc. (NYSE: NR) today announced results for its fourth quarter and year ended December 31, 2010. Total revenues were $194.5 million for the fourth quarter of 2010 compared to $179.3 million for the third quarter of 2010 and $135.5 million for the fourth quarter of 2009. Net income for the fourth quarter of 2010 was $14.8 million, or $0.15 per diluted share, compared to net income for the third quarter of 2010 of $8.2 million, or $0.09 per diluted share, and net income for the fourth quarter of 2009 of $16,000, or break-even on a per share basis.

For the full year 2010, total revenues were $716.0 million compared to $490.3 million for the full year 2009. Net income for the full year of 2010 was $41.6 million, or $0.46 per diluted share, compared to a net loss of $20.6 million, or $0.23 per diluted share, for 2009.

Paul Howes, President and Chief Executive Officer of Newpark, stated, “We are extremely pleased with our strong fourth quarter results, which reflect solid revenue growth in Brazil within our Drilling Fluids business, along with continued growth in the Northeast within our Mats and Integrated Services business. Revenues from our Environmental Services business declined in the quarter due to the expected reductions in waste disposals associated with the Deepwater Horizon oil spill.

“Looking at our full year, 2010 operating income reached a record $78.0 million, an outstanding improvement from an operating loss in 2009. This accomplishment reflects the hard work and dedication of our employees following the challenges of 2009,” added Howes.

SEGMENT RESULTS

The Fluids Systems and Engineering segment generated revenues of $162.8 million in the fourth quarter of 2010 compared to $148.1 million in the third quarter of 2010 and $113.8 million in the fourth quarter of 2009. Segment operating income was $16.8 million in the fourth quarter of 2010 compared to $11.8 million in the third quarter of 2010 and $6.7 million in the fourth quarter of 2009. International revenues rose 41% from the third quarter of 2010, driven by a $14.2 million increase from Brazil. North American revenues were down 1% sequentially in the fourth quarter of 2010 as seasonal improvements in Canada were more than offset by a decline in the Company’s wholesale barite business. Compared to the fourth quarter of 2009, North American revenues increased 51%, while international revenues increased 30%. Operating margin in the fourth quarter of 2010 was 10.3%.

The Mats and Integrated Services segment generated revenues of $20.6 million in the fourth quarter of 2010 compared to $18.2 million in the third quarter of 2010 and $12.4 million in the fourth quarter of 2009. Segment operating income was $10.3 million in the fourth quarter of 2010 compared to operating income of $8.6 million in the third quarter of 2010 and $1.2 million in the fourth quarter of 2009. Revenues for the segment were up 13% from the third quarter of 2010, driven by a $2.2 million increase in rental activity in the Northeast U.S. region. Compared to the fourth quarter of 2009, segment revenues were up 66%. Operating margin in the fourth quarter of 2010 was 50.2%.

The Environmental Services segment generated revenues of $11.1 million in the fourth quarter of 2010 compared to $13.0 million in the third quarter of 2010 and $9.3 million in the fourth quarter of 2009. Segment operating income was $2.6 million in the fourth quarter of 2010 compared to operating income of $3.9 million in the third quarter of 2010 and $1.1 million in the fourth quarter of 2009.
